Case Study: Peak Envelopes Streamlines Communications and Cuts Costs with Korba

 About Peak Envelopes:  

Peak Envelopes is a family-run postal packaging and envelope trade specialist, serving customers across the UK and Ireland. Over time, the business had grown through acquisitions and expanded into Ireland, which left them running on three separate phone systems. In addition, one member of the family had diversified into a separate business, Envibe, which was still tied into the same telecom setup as Peak.

This patchwork of systems made internal collaboration unnecessarily complex and created inefficiencies across the group. Peak needed a modern, unified telephone solution that would simplify communications, support their expansion, and still deliver value for money.


 The Challenge: 

By the time Peak reviewed their telephone system, frustrations had built up on several fronts:

  • Their previous provider had been taken over, and service levels had dropped. The personal contact they relied on disappeared, making it difficult to resolve issues.
  • Their mobile app was unreliable, frustrating staff who needed flexibility.
  • Running three different phone systems was cumbersome and hindered internal collaboration.
  • Costs were higher than necessary, and management knew savings were possible.


 Choosing Korba: 

When exploring alternatives, Peak identified Korba as the provider that could meet all their needs. Korba offered the right balance of flexibility and price, was prepared to support their existing desk phones, and crucially, was able to separate Envibe into its own system while still maintaining quantity pricing across the group.
In addition, Korba was able to consolidate all three existing phone systems into one platform — including the Irish operation. This meant that, for the first time, UK staff could answer Irish phones if required, ensuring continuity of service even when Irish colleagues were unavailable.


 The Result: 

Switching to Korba’s telephone system has delivered significant benefits:

  • Nearly 60% monthly savings (excluding one-off setup costs).
  • Unified communications across the UK and Ireland, with seamless collaboration between teams.
  • Improved call qualitythat enhances both customer interactions and internal discussions.
  • Mobile and desktop apps that allow staff to take and manage calls from anywhere, supporting remote working and flexibility.
  • Dedicated support that is fast, responsive, and restores the sense of personal service that had been missing.

For staff, the system is reliable, easy to use, and full of features that genuinely make their work easier. For management, it has simplified operations and delivered substantial savings.


For Peak Envelopes, choosing Korba was more than just a cost-saving decision. It was an opportunity to bring together a fragmented telecom setup, give staff modern tools to work flexibly, and ensure both Peak and Envibe could operate on systems tailored to their needs while still benefiting from group-level efficiency.
